Like the picture shows:
1) Insert the module rear IDC10 connector on a DIN
rail free slot (there’s only one way to insert the module
because of polarized connector).
2) The module can be fixed on the DIN rail by
pressing the four hooks located on the rear of the
module.

I T RULESNSTALLA ION
The module is designed to be installed, in vertical position, on DIN rail IEC EN 60715. In
order to ensure optimum performance and a longest working life, the module(s) must be
provided with adequate ventilation and no raceways or other objects that obstruct the
v e n t i l a t i o n s l o t s . .N e v e r i n s t a l l t h e m o d u l e s n e a r h e a t s o u r c e s
We recommend installation in the lower part of the control panel.
ADDITIONAL NOTES :
Use in environment with 2 or less pollution degree.
The module complies with the following standards:
EN61000-6-4 (electromagnetic emission,
industrial environment).
EN61000-6-2 (electromagnetic immunity,
industrial environment).
EN61010-1 (safety).
One maximum 2.5A fuse must be installed
near the module.

NOTE: For the best performances, the use of special shielded cables is recommended (BELDEN
9841 cable for example). Terminate the two ends of CANbus network by setting to ON the DIP-
switches, present on the DIN rail connection supports, where the two modules ends are inserted.

CAN BUS RULESCONNECTIONS
1) Install the modules on the DIN rail (max 120).
2) Connect the remote modules using cables of proper length.
The following table shows the datas about the cables length:
-Bus Length: CAN network maximum length as a function of the Baud rate.
Lenght of the cables which connect the two bus terminators modules.
-Drop Length: maximum length of a drop line as a function of the Baud Rate.
(Please see Scheme 1)
